JERSEY, A CGBPORATIQN OF NEW JERSEY LIQUID SPBAYER AND METHOD OF MAKING THE SAME Application filed April 23, 1931.

My invention relates to a liquid sprayer and method of making the same, and it relates more particularly to a certain method of making a suction siphon sprayer including an apron, by which a'great deal of the expense and difiiculty of former methods is eliminated, and by which a minimum of solder is used. 7

An obj ect of my invention is to simplify the 19 construction of suction siphon sprayers' Another object of my invention is to so design a suction siphon sprayer that. the time and expense of making the same is reduced to a minimum while the strength and efficiency of the completed sprayer is greatly increased.

lVith the above and other objectsin view, my invention consists broadly of the novel construction and arrangement of certain parts, whereby they co-act to hold'cach other 49 in place so that by merely slipping each into its own place, it is held by the position of the others: and by sealing the assembled parts with two drops of solder so placedthat the whole is thereby locked into a strong and permanently assembled sprayer ready for use.

For the purpose of illustrating my invention. I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and re liable result-s, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described.

According'to my invention, I provide a hand operated air pump 17 having asheet metal spraying or discharge head1 9 permanently attached to the cylindrical body 18 thereof, by means of the lock seam forming the bead 20, and extending inwardly into the pump, forming a recess 21 between the inner cylindrical wall of the spraying head 22 and the inclined wall 23 and having a flat portion 24: in the same plane as the front circular edge of the bead20 andhaving a central depression 25 therein, and a central discharge aperture 26, through which the air is ejected by the hand-pump.

According to my invention, I also provide a generally semi-circular apron 27 having a circular skirt 28 extending generally transversely thereof and adapted to snap onto the bead 20 of the spraying head, and to interlock or to hook onto the same, and having also a lower straight edge portion 29 adapted to snap into the recess 21 of the spraying head and to be held by the inner cylindrical wall 22 thereof, and having further an inner depression 30 leading to an aperture 31 adapted to permit the passage of the siphon tube 32 therethrough. The apron of my invention also has an outwardly extending front portion 33 adapted to catch and to receive the waste dripping of the spraying fluid, said outwardly extending portion having a slightly raised portion 34 adapted to partially surround and to hold the siphon tube in place against the front fiat portion 24 of the spraying head, as seen more particularly in Figure 11 ;said apron having further a sen1i-circular cut-out portion 35 adapted to permit the free forward ejection of the sprayed fluid.

According to my invention, I further provide container retaining means such as the screw cap 36 for a bottle or other fluid container, such as the can 39 5; said cap having a hole 37 through which the siphon tube 32 passes; a depression 38 adapted to permit the top 40 ofthe cap 36 to lie against the cylindrical wall 18 of the hand pump 17 without interference from the bead 20,'said bead passing into the depression 38; and having also a soldering aperture 41, the function of which will be described hereinafter. r

The siphon tube 32 is of conventional construction having a wall 42 and an inner passageway 43.

In assembly, the apron 27 is snapped onto the spraying head 19 by means of the skirt 28 and the straight edge portion 29 0f the ,apron acting against the bead 20 of the spraying head, and the inner cylindrical wall 22 thereof, respectively.

The siphon tube 32 is then passed through the aperture 31 of the apr0n27; and forced upward between the raised portion 34 of the apron and the flat portion 24 of the spraying head, and pushed into operative relation with the discharge opening 26 of said. spraying head.

In this process, the siphon tubeforces outwardly the raised portion 34 of the apron 27,

thereby creating a tension in the apron, which results in the apron tautly retaining the head 20. In this manner, the siphon tube 32 permanently interlocks the apron 27 with the discharge head 19. The tension thus created, in turn forces the siphon tube 32 against the discharge head flat portion 24 and the outer bead edge 44, thereby holding the siphon tube in place.

The siphon tube 32 is then slipped into the aperture 37 of the cap 36 so that the top cap surface 40 lies flush against the cylindrical body portion 18 of the pump 17 with the solder hole 41 extending towards the pump wall behind the bead, as seen more partieularly in Figure 12. The cap 36, siphon tube 32, and apron 27 are now adjusted so that while in assembled relationship, the cap may lie against the cylindrical pump body 18 and the seam 45 giving the cap a two-line support, as seen more particularly in Figures 16 and 17. Thus the top surface 40 of the cap 36 rests against the seam 45 and against the cylinder 18, eliminating any tendency of the cap to rotate around the cylinder. Solder 46 is then passed from the inside of the cap through and around the solder hole 41 permanently attaching the cap to the cylinder. Solder 47 is also applied to the portion of the siphon tube 32 immediately adjacent the inner portion of the top 40 of the cap 36, eliminating any possibility of the siphon tube 32 being pushed up or down. A suitable sealing washer 48, having a single hole 49 to permit the passage of the washer overthe siphon tube 32 is slipped over the siphon tube 32 and into the cap 36 to seal the upper portion of the cap from corrosion and further to seal the contents of the con tainer 39. In this manner, while the construction of the sprayer is exceptionally strong, no solder is normally visible, either above or inside the cap.

It will be noted that in the process herein described, no solder is applied until all the parts are assembled, and that this assembly is so simple that it may be done in almost an instant, it being merely necessary to snap the apron onto the spraying head, push the siphon tube through the apron into operative relationship with the pump discharge hole and to slip said siphon tube through the thereof, and I therefore desire the present embodiments tobe considered in all respects being had to the appended claims rather than to the foregoing description to inclicate the scope of the invention.
